Fuel needed for grilling a sausage? (3)
I believe the answer is:
gas
'fuel' is the definition.
(gas is a kind of fuel)
'for grilling a sausage?' is the wordplay.
'GAS' is hidden in amongst the letters.
But, I'm uncertain how this is indicated.
'needed' is the link.
Can you help me to learn more?
(Other definitions for gas that I've seen before include "Nitrogen, say" , "State of matter not solid or liquid" , "eg CO2" , "that may quickly be stepped on" , "Oxygen is one" .)
